This invention relates to an adjustable display shelf, and the primaryobject of the invention is to provide a shelf that maybe readilyadjusted to the desired length and fastened on a cash register,anarticle of furniture, a box, a wall jutting, or any other place whereit is practical to fasten a clamp.

A further object is to provide an adjust able shelf of the above kindwhich is simple and durable in construction and efficient in use. I

Other objects will appear as the nature of the, invention is betterunderstood and the same consists in the novel form, combination andarrangement of parts hereinafter more fully described, shown in theaccompanying drawings, and claimed.

In the drawings:

Figure 1 is a to plan view of a display shelf embodying t 1e presentinvention, applied to a wall jutting.

Figure 2 is ,an enlarged transverse section on line 22 of Figure 1. v

Figure 3 is an enlarged fragmentary section on line 33 of Figure 1.

Figure t is a perspective view of one section of a modified form ofshelf embodying ing member for the shelf carried by said section.

The present displayshelf is designed to attractively display articles ofmerchandise at places where ordinary shelves cannot be utilized. Inother words, ordinary shelves involve supporting brackets or pedestalswhich occupy considerable space and often make it impossible toconveniently arrange the shelves, while thepresent invention is 7 devoidof supporting brackets or pedestals which require considerable space andcan be readily clamped to any suitable support.

Referring in detail to the drawings, the present shelf consists of twotelescopingsections 5 and 6, preferably formed of sheet metal, andrespectively having rearwardly projecting clamp arms 7 and 8 rigidlyattached to the outer ends thereof. By sliding the sections 5 and 6relative to each other, the

shelf may be adjusted as to length to roughso ly correspond to the widthof the wall jutting or other support 9 to which the shelf is to beattached, and such adjustment is maintained by suitable means, such as aheaded pin 10 adapted to engage in registered ones 59 of longitudinalseries of openings 11 and 12, respectively provided in the sections 5and 6. One clamp arm has a fixed jaw 13 at the inner side of its freerear end adapted to engage one side of the support 9, while the otherclamp arm has a laterally adjustable jaw 14 adapted to be adjustedagainst the other side of the support 9 and to cooperate with the jaw 13to firmly fasten the shelf in place, either horizontally orslightlytilted, 7

as desired. As shown, the jaw 14 is swivelled on the inner end of anadjusting screw 15 threaded transversely through the free rear end ofthe clamp arm.

Theshelf sections 5 and 6 are formed of 7, longitudinally return-bentsheets of metal so as to be of flattened form in cross section and topresent wide platform portions having flange portions 16 rising from thefront edges thereof to prevent articles from falling forwardly off ofthe shelf and to stiffen the shelf. The sections may be made in this wayas shown in Figures 4 and 5, or they may be shaped to further provideforwardly projecting horizontal ledge portions 17 on the up- {:5

per edges of the flange portions 16, as shown in Figures 1 and 2, toenhance the appearance of the shelf and to receive suitable advertisingmatter. The inner section f. the

shelf has its folds contiguous, while the folds of the outer section 5are spaced apart to snugly slidably receive said inner section 6. Thestructure thus produced is very stiff and durable, and for furtherstiffening purposes the rear longitudinal edge portions'of the upperwalls or folds of the sections 5 and 6 are rolled downwardly to providebeads 18 which telescope one within the other.

The sections 5 and 6 have wings or extensions 19 on the rear outer endportions thereof received in slots 20 provided in the forward endportions of the clamp arms 7 and 8, and passing through these extensionsand the clamp arms are screws 21 or the like by means of which the clamparms are effectively rigidly attached to the shelf sections. Upturnedflanges 22-are provided on the forward outer end portions of the upperwalls or folds of the shelf sections to cooperate with the clamp arms inpreventing displacement of articles from the shelf at the ends of thelatter.

In order to prevent sagging of the shelf intermediate its endswhen anexceptionally long shelf is used or when heavy articles are placed onthe shelf, an intermediate sup porting member may be provided,embodyinga flexible angular plate or bracket 23 having a horizontal armwelded or otherwise fastened to the under side of the shelf section 5 atits inner end and a depending arm arranged to bear against the frontface of the support 9 as shown in Figures 2 and 6. The clamp arms 7 and8 and the depending arm of bracket 23 have suitable friction faces 24:to prevent slipping or inarring of the support.

In use, the sections 5 and 6 are slid relatively to roughly adjust theshelf to a length approximating the width of the support, and

the pin 10 is inserted in registered ones of the openings 11 and 12 tomaintain such adjustment, the rear edge of the shelf is then positionedadjacent the front of the support with the jaw 13 of arm 7 engaging oneside of the support. The screw 15 is then turned to draw the jaws l3 and14 tightly against the opposite sides of the support, thereby firmlyfastening the shelf in place.

It will thus be seen that we have provided a very simple and durableshelf exceptionally well adapted for the intended purpose and uses. Atier of these shelves having different widths would provide foreffective display of small articles, and economy of space under'allconditions of use is insured.

Minor changes are contemplated within the spirit and scope of theinvention as claimed. The depending arm of bracket 23 may be bent to thedesired angle to properly engage the support, whether the latter betruly vertical or not, or whether the shelf be disposed horizontally orat an inclination.

What we claim as new is:

1. An adjustable shelf comprising inner and outer telescoping sectionshaving rearwardly projecting clamp arms rigidly attached to the outerends thereof to grip a support therebetween and means to secure saidsections in their relatively adjusted positions, one of said clamp armshaving a jaw adjustable toward or away from the jaw of the other clamparm. f

2 An adjustable shelf comprising inner and outer telescoping sectionshaving rearwardly projecting clamp arms rigidly attached to the outerends thereof to grip a support therebetween and means to secure saidsections in their relatively adjusted positions, one of said clamp armshaving a jaw adjustable toward or away from the jaw of the other clamparm, said securing means comprising a pin, said sections havinglongitudinal series of openings for selective registration and receptionof said pin. 7

3.
